For the general timelines related to MDR transitional provisions see the illustration.
For specific risk classes of medical devices, stricter timelines may apply in accordance with the applicable regulations.
However, the MDR timelines are subject to review and possible modification as deemed necessary by the EU Commission. Prominent examples:
Due to the COVID-19 crisis the MDR date of application has been postponed by the EU Commission by one year to 26 May 2021 (Regulation (EU) 2020/561).
The transitional timeline for certification obligations for specific class I products has been postponed from originally May 2020 to May 2024. Concerned product groups are e.g. medical device software applications being subject to up-classification (Corrigendum to Regulation (EU) 2017/745 from 25 Nov. 2019)
